Latex-Ficus carica var. Kadota latex was collected from the green fruit of trees grown in the orchard of Mr. V. Ed Scott of Planada, California, as described (1). Subsequent storage and centrifugation have also been described (1). Reagents-Carnation instant nonfat dry milk was used for milk-clotting activity determinations. Barbital was obtained from Mallinckrodt Chemical Works, St. Louis, Miss...

The light doses just above the threshold energy value for inducing the geotropic responsiveness in the roots of Zea mays L., cv. Golden Cross Bantam 70, caused a drastic rise in the NADPH level and a drop in the NADP level in 2-millimeter root tips. Some reducing agents lowered the threshold energy value up to about one-third of the control. From these results, we deduce that light may exert tw...

The number of synapses is a major determinant of behavior and many neural diseases exhibit deviations in that number. However, how signaling pathways control this number is still poorly understood. Using the Drosophila larval neuromuscular junction, we show here a PI3K-dependent pathway for synaptogenesis which is functionally connected with other previously known elements including the Wit rec...
